Metal-to-insulator transition—a process that turns materials from a conductor to an insulator—has been a crucial process behind microelectronic switches, nonvolatile memory, and neuromorphic computing ...

In a surprising discovery, Princeton physicists have observed an unexpected quantum behavior in an insulator made from a material called tungsten ditelluride. This phenomenon, known as quantum ...

Sun et al. selectively excited surface-carriers in topological insulators by directing circularly polarized light at oblique incidence on the surface of the crystal. They determined the resulting ...

University of Cambridge researchers have discovered that a material already known for its peculiar electrical properties appears to behave as both a conductor and an insulator at the same time. This ...

Normally metals and insulators sit at opposite ends of a spectrum of conductivity, but researchers have discovered a material that can switch between those states freely, even at room temperature. The ...

Researchers have confirmed that the spinel compound CuIr2S4, long studied for its unusual metal-insulator transition, becomes ...

Metals are compounds that are capable of conducting the flow of electrons that make up an electric current. Other materials, called insulators, are not capable of conducting an electric current. At ...

Insulator or superconductor? Physicists find graphene is both, at a 'magic angle.' It's hard to believe that a single material can be described by as many superlatives as graphene can. Since its ...

An essential requirement for ensuring worker safety when performing live work with transmission composite insulators (also called polymer or nonceramic insulators) is ...
